IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Letters Patent No. 167,590, datedSeptember 7, 1875; application filed June 15, 1875.

To all whom it may concern:

Be it known that I, WILLIAM VANDEVEN- TER, of Peoria, in the county ofPeoria and State of Illinois, have invented a new and valuableImprovement in'Door Stops and Supports; and I do hereby declare .thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical section ofdoor stop and support. Fig. 2 is a plan view of the same, and Fig. 3 isa front view. Figs. 4 are detailed views.

This invention has relation to improvements in devices which aredesigned to sustain a door, and thereby to prevent its sagging; and thenature of the invention consists of an angular roller-frame, recessed inthe lower face of the door, so as not to project beyond the door-face,in connection with the track-plate provided with inclines and a stop, aswill be hereinafter more fully set forth.

In the annexed drawings, A designates the jamb of a door-casing, towhich is hinged in any suitable manner a door, B. This door is recessedupon its lower partand inner edge, for the purpose of receiving theangular frame U of a supporting-roller, D, which has its bearings in thesaid frame. This frame is secured to the lower edge of the door by meansof a screw or screws, 8.

In practice, the door may be hung in its frame so that its lower edgewill be free of the lintel. In this case the opening thus made will befilled up by a Weatherstrip, a, and the wear of roller D thereon will beprevented by the interposition of a metallic plate, I), which will besecured to the said strip.

When the door is opened, forming with the wall of the house an angle ofninety degrees, roller D will run upon a metallic plate, E, in thenature of a track, which plate is supported by means of a stringer, c,rigidly secured to the floor, within proper distance from the Wall, asshown.. Track-plate E is provided with an upward incline, (1, upon itsfront end, followed by a downwardly-inchned surface, 0, and anupwardly-projecting lug or shoulder, f,- consequently, in mounting therail rollerD will first raise the door slightly in mounting incline d,then lower it in descending incline 0, thereby bringing it in contactwith shoulderf. The

natural tendency of the door to run down incline e, and the slightreact-ion of the hinges of the door, caused by the latter ascendinginclined, will cause it to be securely locked to the plate, and willprevent it from being slammed against the wall by sudden gusts of wind,or its being closed thereby.

It will be observed that the angular rollerframe is recessed in thelower end of the door, so as to afford no obstruction, and be flush withthe door, as shown in Fig. 1 of the drawings.

I am aware that a door-holder, consisting of a pivoted arm provided witha roller, has heretofore been employed, in connection with a spring andstop attachment, and I therefore lay no claim to such invention, whichis objectionable on account of the pivoted roller projecting beyond thedoor, and presenting an obstruction.

What I claim as new, and desire to secure by Letters Patent, is-

The angular frame 0, provided with the roller D, and recessed in thelower face of the door, and flush with it, in combination with thetrack-plate E, having the inclines d e, and stop f, constructed asdescribed, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM VANDEVENTER.
